A plasma addressed display device includes a flat panel, a scanning circuit and a signal circuit. The flat panel is of a superimposed structure of a plasma cell having scanning electrodes in a row configuration and a display cell having scanning electrodes in a column configuration. The scanning circuit sequentially applies selection pulses to the scanning electrode to scan the display panel. The signal circuit writes the picture data in the signal electrode in synchronism with this scanning. On the plasma cells, there are formed reciprocally isolated discharge channels in a row configuration. To each discharge channel, charged with an electrically dischargeable gas, are allotted plural scanning electrodes. As characteristic of the present invention, the scanning circuit sequentially applies the selection pulses to the scanning electrode allotted to a sole discharge channel to produce electrical discharge to form at least two scanning lines to a sole discharge channel. This realizes a high open area ratio and high resolution of the plasma addressed display device. |
